View ChartPolkadot is a blockchain project focused on creating a platform on which other blockchain-based projects and applications can be built. Arguably, it has become one of the most successful projects working to improve the fundamental technology that powers decentralized applications (dApps).
There are thousands of cryptocurrencies across the ecosystem, a vast majority of which can’t communicate with each other. For example, users can’t send their Dogecoin over Chainlink, or vice versa. Polkadot aims to fix that by building a framework that interconnects blockchains, even if each chain performs different functions to one another.
At the center of Polkadot sits the “relay chain,” a central blockchain that connects all other participating blockchains together. The relay chain processes all transactions taking place in the ecosystem at the same time, with the goal of improving scalability.
User-created blockchains that hook into the relay chain are known as “parachains.” By allowing blockchains to communicate with its platform, Polkadot is able to connect many blockchains in a way that wasn’t possible before.
Polkadot relies on Nominated Proof-of-Stake (NPoS), a method of validating crypto transactions based on how many coins each participant has put up as collateral.
Many regard Polkadot as one of the most promising networks of the future, as it is attempting to lay the groundwork for a variety of applications. Although the project is still in its infancy, numerous developments suggest that its approach could become the standard for developing Web3.
However, Polkadot may not become the go-to platform for developing blockchain-based applications, particularly given that Ethereum is releasing its own improvements that address many of the same issues. However, the combination of the Substrate development tool and the fundamental technical benefits could attract a lot of development.
